AI Thread Summary
To calculate the combined weight of the truck and ferry boat, the buoyant force must be considered, which equals the weight of the displaced water when the truck is on the ferry. The ferry's dimensions allow for the calculation of the volume of water displaced when it sinks 4.00 cm. Users are encouraged to demonstrate their understanding by showing initial attempts at the problem, as this forum prioritizes learning through engagement. Providing relevant equations and explaining their connection to the problem is essential for receiving assistance. Overall, active participation and effort in problem-solving are necessary for effective help in this forum.

Homework Statement



A ferry boat is 4.0 m wide and 6.0 m long. When a truck pulls onto it, the boat sinks 4.00 cm in the water. What is the combined weight of the truck and ferry?

Homework Equations



Buoyant force = Weight of the floating object

The Attempt at a Solution



How would I find the weight when I don't know the mass of either object? I don't know what equation I would use or how to get started on the problem...

Welcome to PF bor33d. This is a great place to get homework help but you have to understand that we have rules here. You have not shown ANY attempt on the problems you have posted in this forum. (I have seen your other threads.) The rules are that you must show some work before you get help here. I know you are not far enough along to do any calculations in these problems, and that is fine, but you still need to show some effort. For instance, in all of your problems you have posted formulas that do apply the the problem. Why did you decide to post them? How do they relate what your given and what you need to find?Sorry, but if I just told you what equations to use, you wouldn't get anything out of this thread or your others.

So show me some of your thoughts on this problem.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
